ACM604P, 4 x 60 Watt Power Amplifier

Product Description

The ACM604P is a four channel (4 x 60w) power amplifier designed for commercial installations. The one unit contains
four independent 60 watt amplifiers for multi-zone applications. The ACM604P can be used for either low impedance (8
ohm) or 70v/100v line speaker systems per channel. The amplifier can be mounted in a standard 19” equipment rack (rack
ears supplied) or it can be used on a shelf or table. The ACM604P features a line level input (with parallel output) per
channel and is normally used with mixers, mixer amplifiers or other power amplifiers.

Front Panel Features

Power Switch

The black rocker switch on the right hand side of the front panel is used to switch the amplifier on and off. The ‘up’
position is on. When the amplifier is connected to an appropriate AC power source and is switched on, the blue power
LED will illuminate.

On LED

The blue “On” LED above the power switch will illuminate when the amplifier is connected to mains power and is
switched on.

Signal LED

The green “Signal” LED’s located next to the On LED indicate that the ACM604P is receiving audio signal via its line
level inputs. One LED is provided per channel. The signal LED’s are a simple way of trouble-shooting installations
especially in multi amplifier projects. At a glance the signal LED’s will indicate that audio is reaching the amplifier .

Rack Mounting

The ACM604P is supplied with rack ears attached to allow mounting within a standard 19” equipment rack. As is the
case with almost all audio products, adequate ventilation and air flow is required. When installing multiple ACM
amplifiers within the one rack, it is recommended that at least 1 rack unit of ventilation space is left between every two
amplifiers.

For table or shelf mounting, the rack ears can be removed using a screwdriver. Once the rack ears are removed, please
reinstall the screws.
